ABSTRACT:
An adjustable hydrostatic drive, particularly for the auxiliary units of motor vehicle internal combustion engines, has a pump/motor unit (2, 3) with the pump and motor arranged radially one within the other in a common housing (1) with an eccentric control ring (6) between them. The pump and motor are hydraulically connected together and have delivery volumes adjustable in opposite senses. The speed variation mechanism includes a shaft (14) driving the pump/motor unit (2, 3) which passes through the side plates (17) of the housing and rotates with one projecting end (20) in a bushing (22) having an eccentric, sickle-shaped shoulder (21) that engages in a through bore (23) in a front face (30) of the control ring (6) and an outer bushing (24) that coaxially surrounds the shaft end bushing and includes a nose (25) which projects into a radial groove (26) in the control ring (6).
